AstroZap 12" Truss-Tube RC Dust Cover - 14" Diameter - AZ1412
When it comes to keeping the optics of their telescope clean, Astronomers can be justifiably meticulous. Dust is everywhere, and the accumulation of it on the primary and secondary mirrors brings down overall image quality. But you don't have to let dust reach your optics between observing sessions. Proudly made in the USA, the material used to make this dust cover comes from a blend of nylon and cotton. A sewn elastic strap allows it to fit securely over the open end of a Truss-Tube RC telescope. This keeps dust from accumulating on your optics, leading to clearer images.
